caused by the firing of a bullet into the pendulum bob. Let L = 1.5 m and mA = 7.5 kg. For George Washington’s 0.58-caliber pistol, which fired a roundball of mass mB = 87 g, it is found that the maximum swing angle of the pendulum is θmax = 46°. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Bullet B fired from a gun secured on a stand hits block A attached to a vertical rod of length L pivoted at the top.The illustration indicates that, after the impact of the bullet, the block
The ballistic pendulum used to be a common tool for the determination of the muzzle velocity of bullets as a measure of the performance of firearms and ammunition (nowadays, the ballistic pendulum has been replaced by the ballistic chronograph, an electronic device). The ballistic pendulum is a simple pendulum that allows one to record the maximum swing angle of the pendulum arm caused by the firing of a bullet into the pendulum bob. Let L = 1.5 m and mA = 7.5 kg. For George Washington’s 0.58-caliber pistol, which fired a roundball of mass mB = 87 g, it is found that the maximum swing angle of the pendulum is θmax = 46°. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Bullet B fired from a gun secured on a stand hits block A attached to a vertical rod of length L pivoted at the top.The illustration indicates that, after the impact of the bullet, the block moves upward to the right through an
